【delphi|Delphi的StringReplace】
function StringReplace (const S, OldPattern, NewPattern: string; Flags: TReplaceFlags): string;

rfReplaceAll：全部替换
rfIgnoreCase：忽略大小写

For Example：

var
aStr: String;
begin
aStr := 'This is a book, not a pen!';
ShowMessage(StringReplace (aStr, 'a', 'two', [])); //This is two book, not a pen!只替换了第一个符合的字
ShowMessage(StringReplace (aStr, 'a', 'two', [rfReplaceAll])); //This is two book, not two pen!替换了所有符合的字
aStr := 'This is a book, not A pen!';
ShowMessage(StringReplace (aStr, 'a', 'two', [rfReplaceAll])); //This is two book, not A pen!只替换了符合的字(小写a)
ShowMessage(StringReplace (aStr, 'a', 'two', [rfReplaceAll, rfIgnoreCase])); //This is two book, not two pen!不管大小写替换了所有符合的字
end;
